1 Claim. 1

This invention relates to a loom shuttle conruction, and more particularly to the construction of the shuttle block thereof.

The primary object of the invention is to provide a shuttle block having means for tensioning and guiding the filling from the shuttle, as the filling feeds from the shuttle, thereby resulting in the pulling of the filling in a straight line and consequently eliminating breaks in the filling, jerk-ins and broken picks, with the result that a smooth flawless cloth is produced.

Another object of the invention is to provide a tensioning device for shuttle blocks that may be adjusted to accommodate fillings of various gauges to meet various requirements of use.

Still another object of the invention is to provide a guide and tensioning device which may be readily applied to the shuttle blocks now in use, eliminating the necessity of making extensive alterations in the shuttle block construction to mount the tensioning and guide device.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure 1 is a perspective view of a shuttle block equipped with a filling guide and tensioning device, constructed in accordance with the invention.

Fig. 2 is a longitudinal sectional view through the shuttle block.

Fig. 3 is a sectional view taken on line 33 of Fig. 2.

Referring to the drawing in detail, the body portion or shuttle block is indicated generally by the reference character 5 and is provided with the usual pointed end 6.

The forward portion of the body 5 is cut away at 1, one wall of the cut-away portion being formed with the filling opening 8 through which the filling is extended to the nose of the shuttle block.

Extending across the cut-away portion 7, and arranged in vertical spaced relation with each other, are the horizontally disposed supporting pins 8 over which the spring 9 is looped providing a plurality of spaced parallel loops [0, between which the filling runs, in passing through the shuttle eye. with respect to each other that the spaces between the loops will set up slight pressure with the filling passing therethrough, to hold the filling taut The loops l are so arranged 2 under an even tension, to eliminate any possibility of kinky filling, jerk-ins," and broken picks,

Associated with the spring 9, and arranged in parallel spaced relation with the loops thereof, is the guard Wire II that extends an appreciable distance beyond the upper and lower ends of the loops In, as clearly shown by Fig. 2 of the drawing, the guard wire extending over certain of the loops, to prevent the filling from being fed laterally between the innermost loop, and wall of the cut-out portion, to bind and prevent the feeding of the filling from the shuttle block.

As shown by Fig. 3 of the drawing, the pins 5' are positioned in openings formed in the walls of the cut-away portion 1, and these pins are held in place by means of the threaded plugs [2 that are positioned in threaded bores formed in the shuttle block, with the inner ends thereof bearing against the pins. Due to this construction, the pins may be readily removed, should it be desired to remove the spring to substitute a spring formed into loops so spaced apart as to receive a filling of different size.

In use, the filling A is extended through member I3 and then is threaded through the eye of the shuttle block in the usual and well known manner and passes through the guide or tension spring tensioning the filling.

Having thus described the invention, what is claimed is:

A shuttle block comprising a body having a forwardly extended nose piece over which shuttle filling passes, said body having a vertically disposed cut-out portion arranged adjacent to the nose piece, a pair of supporting pins disposed horizontally across the cut out portion of the shuttle block, means for removably holding said pins in position, a length of wire material looped around said pins providing a plurality of spaced spring loops between which filling from a shuttle is fed, and a guide wire extending into the wall of the cut out portion and overlying certain of said loops, holding the filling passing between loops in spaced relation with the wall of the cut out portion.
